People like to say that President Obama, even Senator Obama, is treated like a rock star and surrounded by adoring crowds. He may have crowds who cheer for him, but it's not because he screens others out.
Gov Romney is using the Rove method he perfected with Pres Bush, the "Home on the Range" method, where seldom (make that never) is heard a disparaging word. He's never been corrected. He's been allowed to say what he likes and anyone who knows otherwise knows enough to stay quiet.
I know, it's hard work. Whatever.
